Thyroid Scan (Definition)

The patient ingests radioactive iodine or has intravenous injection of radiotracer technetium to define structure, size, and function of thyroid gland. Overactive ( hyperthyroid) normal, and underactive thyroid glands are determined. Sometimes autoimmune conditions and tumors of the gland can be suspected. Correlative imaging ultrasound, mr imaging, and blood tests ...Read more

Get thyroid labs: You most likely already have your thyroid levels checked. If not, you need to get thyroid labs drawn. From the uptake and scan above, your TSH should be low, which indicates hyperthyroidism. The treatment is 1)antithyroid drug, 2)i-131 ablation, 3)surgery. With itp, maybe hold off on surgery for now. Please discuss all of this with your doctor. Good luck. ...Read more

How many days does a thyroid uptake scan take?

How many days does a thyroid uptake scan take?

One or two days: The thyroid scan can be performed either with iodine 123 or iodine 131. The scan itself is very rapid ( approximately 10 minutes). According to the type of radioiodine used, it is faster ( same day) with 123iodine or we need to wait 24 hours in the case of 131 iodine. Usually the thyroid uptake is performed with 131 iodine and the thyroid scan is performed with 99mtc-pertechnetate ...Read more

Will the radioactive iodine capsule work for my thyroid uptake scan?

YES: An uptake value will be established. Uptake can be low, normal, or high. Scan will be diagnostic if enough iodine localizes in the thyroid gland. Large amounts of stable iodine from iodized salt and ocean seafood can compete with radiodine and decrease uptake. ...Read more

I've done a thyroid u/s. Dr. Called and said they found 2 thyroid nodules. Now i'm going for a thyroid uptake scan. What will this test do or show?

Hot or cold: Thyroid nuclear scan usually with iodine 123 will show whether nodule is active (hot, increased uptake, or nonactive (cold, decreased uptake).More cold nodules are cancer.For patients presenting with thyroid nodules greater than 1 cm. In diameter (up to 20% will be malignant). They should be carefully evaluated, and managed. If greater than 1 cm. Should be closely followed or biopsied. ...Read more

My thyroid uptake scan showed a cold nodule but TSH is normal. Will it need to be removed? It's taking long to see an endo and lab rec''s fna.

Depends: Next step would usually be a thyroid ultrasound and fna. If the, "nodule" is a simple cyst (colloid cyst) then it will likely be aspirated, if a solid nodule it would be biopsied. Most of the time a solid nodule will be negative for malignancy. If positive for malignancy, surgical removal would be the norm. ...Read more
